Abstract
The magnetic pole device of the present invention has four polar magnets and any number of interpolar magnets adjacent to and in between said polar magnets. The interpolar magnets are positioned to progressively rotate towards the orientation of the four polar magnets. Such a magnetic device would create an even flux within a liquid sample and cause the radial movement of magnetized particles toward the inner wall of the surrounding magnets.
